1 In laundries orl similar establishments *where'it is'necessary-to transfer bags'of laundry or other articles from one Tplace to another onrthe same floor Aor levelor from one level f 5 to another, diiiiculties'have'been-encountered due to the tact that' the conveyer carriages at y 'presentin'usefarenot constructed to permit "said 'carrlages'tobe lconducted around curves y1n aconveyer-ral or trackand also' up' 1nf n vclines from oneielevation'tol another without 1 said conveyer carriages binding or 'clamping inclined portions thereof.

This inventionjhas been devised for the pur- "the rail at either "the curved or the upwardlyv 15-fposefofp'rovidinga conveyer carriage of the roller type which is adapted for use in travel- -ii'ngi around curves ina conveyer rail without i bindingfor clamping as' lwell as being adapted forA travel'overupwardly inclined Vsections of T a conveyer rail without fanyfbind-ing or lockaing action taking-place between `thecnveyer carriage and the inclined-sections of the rail.

This invention (in a preferred form) is illust-,rated in the drawings and hereinafter more fully described.y

On the drawings:

Figure l is a front elevation of a conveyer carriage embodying the principles of this invention showing a sectional portion of the supporting rail on which the carriage is engaged Figure 2 is a sectional View of the conveyer carriage taken on line Il-II of Figure l illustrating in dotted linesk several different possible positions of the carriage with' respect to the rail.

.top section comprising an arcuate plate l and inwardly converging flanges 2 and 3. 'A b0ttom frame section comprising c an arcuate plate 4' havlng integral converging flanges y5 and 6 formed thereon is lintegrally connected with the upper frame section by lmeans of afconnecting web or plate 7 which integrally unites the flanges '3 and' of the upper and lower framey sections, respectively. Rotaty'ably mounted l'or journaled on the inner face of the upper frame section flanges 2 and 3 are a pair'of rollers 8 disposed at substantially rightangles `to one another with the peripheries of said rollers positioned at an angle with one another adapted to be engaged von the two upper edges of a conveyer track y-or r'ail 9. Rotatably journaled 'on the inner kgfaces `im? the lanoes rand ofl the lower anged section 'of5 the .Carriage isa-pair of lower rollers 10 also disposed substantially at right angles with respect to one another to position the peripheries thereof at substantially right angles to permit the peripheries of said rollers to engage or track on the two lower edges of the conveyer track or rail 9, as clearly illustrated in Figure 1. -The conveyer rail 9 is adapted to be supported on a supporting framework or bracket 1l of any Vdesired construction. The improved conveyer carriage is adapted to be mounted in place upon the conveyer rail 9 by simply/removing either one of the rollers from the flanges 2 or 5 of the framework. VViththe-` removal of one of said rollers it will be noted If desired, the lower edge or margin of the f rail 9 may be provided with a notch at any desired point permitting the conveyer icarriage to be readily mounted in place without requiring removal of any of the rollers. Supported on the middle portion of the arcuate plate 4 of the lower frame section is a hook member 12 on which a bag of laundry V13 or other article which is to be conveyed may be removably engaged to permit the bag of laundryto be transferred along the conveyer rail 9 from one place to 'another either on theV same level or from one floor or elevation to another without any danger of the'conveyer carriage binding or clamping against the rail at curved sections similar to 14 (Figure 4) or on upwardly inclined' sections such as 15, illustrated in Figure 3. y f

The peculiar arrangement of the two groups of rollers 8 and 10 at an angle to the corners and edges'of the rail 9 permit the conveyer carriage .to haveV free movement on said rail 9 so that the carriagemaybe moved into dierent positions, such as the vdotted line position illustrated in Figure 2. This novel arrangementof the rollers at an angle with respect to one another and with respect to the corners or edges ofa conveyer rail provides a conveyer carriage of substantially a universal type permitting the conveyer c arriage to not only be adapted for use as a gravity conveyer carriage, but permits the carriage or trolley to conveniently travel around curved sections 14 aswell as upwardly over inclined sections leading from oneY lelevation to another without any possible danger of the conveyer carriage clamping or locking on the irregular sections of the conveyer track or rail.

While the rollers are described as being positioned at substantially right angles to one another, it will, of course, be understood thatsaid rollers may be mounted at any desired angle depending upon the type of rail which is to be used. Y

I am aware that many changes may be 'l necessitated by the prior art.

I claim as my invention: 1. A conveyer carriage comprising a framework having an Yopening in one side thereof,a carrier thereon,- and a plurality of f rollersrotatably mounted in said framework with the peripheries of said rollers positioned at an langle'with respect'to one another.

2. A l vconveyer carriage comprising a framework having a plurality of-inclined sections forming a part thereof, a carrier on said framework, and a plurality of rollers rotatably mounted withinthe framework on framework, a carrier thereon,and-a plural# ity of pairs of rollers mounted within said framework with the rollers of each pair Vdisposed at substantially right! angles with vre-v spect to one another and with respect Vto the rollers of an adjacent pair.

v 4. The combination with a conveyerrail, of a conveyer carriage movably mounted thereon and comprising anvopen framework, anda plurality of pairs of rollers rotatably mounted in said framework adapted to track on the upper and lowerlongitudinal edges of said conveyer rail. v

5. The combination with a conveyer'rail, of a conveyer carriage engaged thereon, and four rollers rotatably mounted in said framework to permit the peripheries of said rollers Vto'engage the four longitudinal edges of said conveyer rail. Y f 6.,A conveyer Ycarriage ofthe classvdescribed comprising a pair of flanged sections,`

means for integrally connecting said sections l y said inclined sections with the peripheries of one to the other to form a framework having lan opening in one side thereof to permit mounting of the conveyer carriage, and a pair :of rollers rotatably mounted "in each of-ff said'flanged sections with the peripheries of saidrollerspositioned at an angle with respect to one another to permit eachpair of lrollers to have rolling contact withv a 'pair of longitudinalv edges of a conveyer rail.Y

7. A conveyer carriage comprising a framework having an opening 1n oneside thereof to facilitate mounting of the carriage,

a carrier supported on said framework, and

, two pairs of rollers rotatably mounted in said lso frameworkwith the rollers positioned to i permit the four Vrollers to track on four of the longitudinal edges of a conveyer rail.

framework having four converging wal s, a

8. A conveyer carriage comprisin a carrier on said framework, and a roller rotatably mounted on each of said walls, said rollers adapted to track on the four longitudinal edges of a conveyer rail.

9. The combination vwith a conveyer rail, of a conveyer carriage having an opening in one side thereof to facilitate mounting of the carriage around said rail, and rollers mounted in said carriage above and below said opening to track on the upper and lower longitudinal edges of the rail.

. In testimony whereof I have hereunto subscribed my name at Milwaukee, Milwaukee y County, Wisconsin.
